PROCESS FOR THE SEPARATION OF OLEFINS AND LOW MOLECULAR WEIGHT HYDROCARBONS IN METHANOL TO OLEFIN PROCESSES

PROCESS FOR THE SEPARATION OF OLEFINS AND LOW MOLECULAR WEIGHT HYDROCARBONS IN METHANOL TO OLEFIN PROCESSES

A process of purifying downstream methanol-to-olefin streams comprising separating a downstream methanol-to-olefin stream comprising one or more light and heavy components in a first column into a light component stream and a heavy component stream, purifying a light component stream with a first di...

Zusammenfassung:A process of purifying downstream methanol-to-olefin streams comprising separating a downstream methanol-to-olefin stream comprising one or more light and heavy components in a first column into a light component stream and a heavy component stream, purifying a light component stream with a first dividing wall distillation column thereby producing an ethylene fraction and distilling the heavy component stream thereby forming a propylene fraction.
